You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

The gate at the top of the stairs still wore its padlock, and the padlock still wore forty years of rust. Quinn crouched to look at it, penlight in her teeth, while the generator hummed somewhere below and threw stuttering white light up the tiled throat of the stairwell. "Cut?" she asked around the torch. "Intact." DC Ade Fowler leaned against the tiles with his hands in his coat pockets, careful not to touch anything. "Transport for London says the only key lives in a drawer in Southwark and hasn't left it since the Blair government. We got in through the ventilation shaft off Hawley Crescent. Fire brigade opened it for us." "And that shaft has a grille." "Bolted. From the inside." Quinn took the penlight out of her mouth. "Then how did our victim get down there, Ade?" "Same way anyone gets anywhere in Camden. Badly." He pushed off the wall and started down after her. "Fifty quid says there's a route we haven't found. These stations leak. Kids get in, urban explorers, the trainspotter lot with the head-torches. Half of them post the videos." "Show me the video." "Give me an hour." The stairs went down further than she remembered stairs going. Halfway, the air changed — colder, dry, with something under it, sweet and burnt, like a bakery that had caught fire a week ago. Her breath started showing at the bottom step. The platform had been dressed for something. That was the first wrong thing. Iron hooks stood screwed into the old advertising frames, thirty or forty of them, each one bright and unrusted against the ruined tiles. Sockets pocked the platform floor in two neat rows, drilled clean, the kind of holes you'd sink a market stall post into. Someone had swept. Sixty years of dust and rat leavings and paper flakes lay banked up along the walls in tidy grey berms, and the centre of the platform was bare enough to eat off. "Right," Fowler said. "So: rave." "Sorry?" "Illegal party. Sound system, stalls flogging pills and warm cider, someone charges a tenner on the door. They tidy up because the whole business only works if nobody knows. Then a deal sours, our man gets stuck, and everyone legs it." He gestured at the hooks. "Lights hung off those. Bunting. Whatever." Quinn walked the row of drilled holes. She counted eleven on the northbound side before they stopped, resumed, stopped again. "Ade. Where are the cables?" "They took them." "They took the cables and the sound system and the cider and left the hooks." She squatted at the nearest hole and put her little finger in it. Dry. No grit at the bottom, no rain-wash, no cobweb. "These were drilled and used and pulled out and the holes are clean. How many times?" "How many—" "There's wear on the lip. Look at it, don't nod at me." She moved her torch so the beam raked sideways and the shadow filled the socket's rim, showing the shallow bevel worn into the concrete. "Post goes in, post comes out. In, out. Dozens of times. This wasn't one party. This was a routine." Fowler's jaw shifted. "Squatters, then. Long-term." "Squatters cook. Squatters shit. Show me a fire scar. Show me a bucket." He didn't. The body lay in the mouth of the northbound tunnel, forty feet along, arranged the way a man lies when he's fallen from standing — one arm folded under, the other flung, the cheek pressed to the sleeper. Male, sixties, silver stubble, a coat that had cost money when Quinn was in uniform. The scene photographer had finished and was packing up, breathing through his mouth. Quinn stood at the tape and let her eyes do the work before her feet did. "Cause?" she asked. "Pathologist's guessing exsanguination." Fowler consulted nothing; he never wrote anything down until it was over. "Big wound, right side of the neck, edge to edge. Looks like a blade." "Where's the blood?" "There's blood." "There's a smear." She ducked under the tape, set her boots on the plate the CSIs had laid, and crouched by the man's shoulder. The wound gaped, clean-lipped, four inches, and the collar of the good coat was stiff and dark. Under him the sleeper had a stain the width of a dinner plate. "A man that size holds nine, ten pints. Cut him there and he'll paint the tunnel to shoulder height. Arterial spray, Ade. It goes up. It goes across. Where is it?" Fowler crouched too, on the other side, and looked at the ballast for a long moment. "Moved," he said. "Killed him somewhere else, dumped him here." "Drag marks?" "None." "Footprints?" "That's the thing." He almost smiled, and she hated that he almost smiled, because it meant he'd been holding something. "Come and look at the dust." They walked back to the platform edge together. Fowler crouched and swept his torch flat across the swept concrete, and in the low raking light Quinn saw them: prints, dozens, scores, layered — bare feet, boots, something narrow with a long heel — all pressed into the fine grey film that had settled since the last sweep. All pointing one way. "Out," Quinn said. "Every single one. Towards the ventilation shaft, towards the stairs, towards the crossover tunnel. Nothing comes in. Not one print heads down that platform from the entrances." Fowler stood and wiped his palms on his coat. "Which is impossible, so it's staged. Someone's walked it backwards, brushed it, played silly games to waste our time." Quinn didn't answer. She had gone still — the stillness her old sergeant used to call the off switch, the thirty or forty seconds where she stopped being in the room. Because the prints weren't wrong. They were incomplete. A crowd had left. A crowd had not arrived. And the sweeping berms along the walls were on both sides, uniform, undisturbed — nobody had brushed the floor after the crowd went, because the crowd's prints were still there. "Ade. What time did the call come in?" "Anonymous. Nine forty. Female, young, well spoken, sounded like she was reading it out. Gave the location by name — 'the platform under Hawley Crescent' — and rang off." "Ring back?" "Phone box on Kentish Town Road. There's about four left in London and she found one." "Full moon last night." Quinn said it to herself, then heard herself say it, and something behind her sternum went cold in a way the tunnel hadn't managed. "Sorry?" "Nothing." She turned back to the body. "Pockets." "Empty. No wallet, no phone, no keys. Watch on him, though — decent one, so not robbery. Stopped at twelve past two." Quinn glanced at her own wrist, out of habit, and the worn leather strap sat where it always sat, and the hands underneath it had stopped at twelve past two. She looked at it for three full seconds. Then she pulled her sleeve down over it. "Bag anything odd?" "One thing." Fowler beckoned an exhibits officer, who came over with a clear pouch and held it up. Inside sat a disc of bone, yellowed, no bigger than a ten-pence piece, drilled through and scratched with a mark like a bird's footprint. "It was in his mouth. Under the tongue. Pathologist found it when she checked the airway." Quinn took the bag. Turned it. Held it to the light of the generator lamps, and the scratched mark caught and threw back more light than a bone should. "Coin for the ferryman," Fowler said. "Some ritual nonsense. Gang thing, maybe — a message." "It's not a coin." Quinn tilted it. "There's no face. No value. It's cut to a size, drilled off-centre, and the edge is worn smooth on one side only — the side a thumb would rub." She held it up so Fowler had to look. "That's not a message, Ade. That's a ticket."
